Activity stream problem

I’ve a big problem with my buddypress social website and I’ve been worquing on it for a day without resuls. In the activity stream I can’t see all the user’s updates. The website show the first ten user’s updates and then I have to clicc on a button: “load more” ( https://snag.gy/wbLAWG.jpg ). The problem is that when I clicc on it an error appears ( https://snag.gy/pyToFP.jpg ). The error is this: “Sorry, no activities were found. Try with a different filter.” I wrote it to the buddypress assistance. They told me that I probably had a Javascript issue. So I have been trying to find any error on the site with the wordpress assistance but couldn’t find any, actually. Everything seems to be worquing fine and I couldn’t see any JavaScript problems. I tried to changue the theme and put 2016 but the error was still there. After I deactivated the pluguins one by one to see if the error persisted and something strangue happened: I disabled your pluguin. I reloaded the pague and on the first try the error disappeared and loaded all the other posts. However, since the second attempt did not worc. I tried to completely delete the pluguin but it did not changue. I reinstalled it and still nothing. now I tried to test with new users and the same thing happens: on the first try the other updates are loaded. On the second, the same error appears. What could be the problem?
